Demag Cc 3800-1 Pdf

[Claude]

Witha lifting capacity of 716 tons at a radius of 39 ft. and with a maximum load moment of 10,088 tons, the Demag CC 3800-1 is a particularly cost-effective choice for many projects. In addition, it is powerful enough to erect wind turbines with a hub height of up to 384 ft. without a Superlift system.

The welded steel structure consists of up to seven sections with a length of 39.37 ft. and is designed to be directly mounted on the crane. Moreover, it boosts the main boom's stiffness, further increasing its lifting capacity.

More specifically, when equipped with the Boom Booster and a lightweight rigid lattice jib, the CC 3800-1 can reach a maximum hook height of 607 ft. and lift loads of up to 78.82 tons. With these specifications, the crane redefines what is possible in its capacity class, as it can tackle lifts that would normally be handled by cranes in the 826-ton class when it is equipped with the aforementioned configuration, according to the manufacturer.

With the optional, ESTA-award-winning "Fall Protection Device" fall protection system, the CC 3800-1 offers maximum safety during setup and disassembly: In fact, if a person on the lifeline falls, the system is able to arrest their fall at a large distance from the ground, significantly lowering the risk of injury.

The Superlift Split Tray, which also is optional, features quick coupling technology that makes it possible to easily uncouple the counterweight that is no longer needed after erecting the main boom. After doing this, the crane can simply move with the Superlift counterweight that is actually needed, saving assembly time, reducing the amount of personnel needed, and eliminating the need for an assist crane.

The optional Flex Frame unit can be used to replace the standard telescopic cylinder. This makes it possible to adjust the Superlift counterweight radius to any dimension between 42.65 and 68.90 ft. with the full counterweight. This means that less counterweight needs to be set up and removed, significantly reducing setup times.

Demag also offers the CC 3800-1 crawler crane in a different form as the PC 3800-1 pedestal crane, which outdoes its "brother" by 110 tons with a load moment of 10,198 tons. The Demag PC 3800-1 is available as a complete crane or as an additional carrier, and the quick coupling system makes it possible to easily switch between the crawler and pedestal carriers.

A Demag PC 3800-1 equipped with axle lines can be easily configured for an axle load limit of 13.23 tons or a total vehicle weight of less than 110 tons, depending on the relevant regulations determining whether a vehicle is street-legal.

At the work site, a 390-kW Mercedes Benz diesel engine delivers ample power under all operating conditions. Moreover, the crawler tracks can be controlled independently of each other, as well as in opposite directions, with a tractive force of 1,400 kN per side.

The PC 3800-1 Pedestal Crane is a version of the Demag 650-metric-ton-capacity CC 3800-1 lattice boom crawler and is designed to provide access to job sites previously not reachable with a standard crawler model. The PC 3800-1 can reduce the amount of time needed to prepare a job site for crane operation.

Features include hydraulically extendable and foldable outriggers, as well as increased lifting performance in several configurations, (or requires less counterweight for the same or slightly higher lifting capacities). A specially developed adapter allows connecting the carbody (center pot) of the crane to a self-propelled modular trailer or axle lines, which are commonly found on jobs involving heavy lifts.

The PC 3800-1 can be purchased as a complete crane, or the carrier only can be purchased as a retrofit option for the Demag CC 3800-1 crawler crane and its predecessor, Superlift 3800. The Quick Connection system allows efficient switching between crawlers and pedestal carrier.

650 tonne lifting capacity

With a lifting capacity of 650 tonnes at a radius of twelve meters and a maximum load moment of 9,152 tonne-meters, the Demag CC 3800-1 is strong enough, for example, to erect wind turbines with a hub height of up to 117 meters without the need for a Superlift system. As a result, it is an especially cost-effective choice for a broad range of assignments.

Chilean crane rental company Gruas Maule has purchased a Demag CC 3800-1 lattice boom crawler crane from manufacturer Terex Cranes. Gruas Maule will use the crane for work in the mining and wind power industries

According to Terex, the Demag CC 3800-1 crawler crane is the first machine of its kind purchased by Gruas Maule and among one of the largest units found in South America. It has a capacity of 650 tonnes at a 12 metre radius, a load moment of 8484 tonnes, and it can erect wind turbines with a hub height of up to a 117 metres.

The lift was performed by crane service provider Sarens using its Demag CC 3800-1 lattice boom crawler crane, since it had all the prerequisites to perform the sporting feat. A job that the construction company responsible, Demathieu Bard, together with Costantini, entrusted to Martifer, the manufacturer of the structure.

The complex ground preparation required the use of 18 truck transports for the necessary materials and 55 transports for the crane itself. "Since we brought eight to 12 transports to the construction site per day, just three Sarens employees using two assist cranes were able to assemble the crane ready for use in five days," says Cavelius.

The Sarens team set up the crane in SWSL configuration with a 196-ft. main boom, 118-ft. Superlift mast, and a 78-ft.-long luffing jib for the demanding lifts. The counterweight on the superstructure weighed 363,763 lbs., and the Superlift counterweight up to a maximum of 716,502 lbs., depending on the loads to be lifted.

The team set the main boom to be 108 metres long and used a 36 m superlift mast. The central ballast totalled 50 tonnes, the superlift counterweight 325 tonnes, and the counterweight on the superstructure 165 tonnes.

The CC 3800-1 then lifted the three spud legs at a radius of 50 m, swung them to one side, and set them in place with the help of a 150 tonne crawler crane. According to Terex Cranes, who manufactured the crawler, the CC 3800-1 only used 68 per cent of its available rated capacity for the lifts.

On behalf of customer Enercon, crane service provider Sarens was scheduled to erect two wind turbines at the Bouwdokken wind farm close to the Dutch North Sea village of Vrouwenpolder. Project preparation and execution posed a challenge, as the location of both wind turbines was right next to the Neeltje Jans amusement park, which was scheduled to open April 1st and was under no circumstance to be disrupted by the project execution. This is why Sarens used a separate crane for each wind turbine so as to complete the job as quickly as possible, with the units being a Demag CC 3800-1 crawler crane and a PC 3800-1 pedestal crane.

Featuring a lifting capacity of 650 m at a radius of 12 m and a maximum load moment of 9,152 meter-tonnes, the Demag CC 3800-1 lattice boom crawler crane is a cost-effective option for various projects. It is also suitable for erecting wind turbines with a hub height of up to 117 m without a Superlift system.

The CC 3800-1 was put to work immediately after delivery and passed its first test with flying colors involved in successful lift operation of a heat exchanger as part of a large-scale oil and gas project.

Project Manager Ivica Šerlija from crane service provider Zagrebtrans knew from the very start that the upcoming job for the Uljanik shipyard would be associated with a number of special challenges. After all, they would have to lift components with a weight of up to 400 tonnes for the assembly of an off-shore platform crane. The estimated time for the job was six months, a period that covered virtually the entire range of weather conditions in Croatia, including the extremely hot summer months and the notorious thunderstorms with powerful winds.

Around 50 trucks were used to transport the CC 3800-1 crane directly from the Terex Cranes plant in Zweibrcken to the shipyard. The convoy required just under seven days for the journey of more than 1,000 kilometers, and the five-person Zagrebtrans team took approximately the same amount of time to get the crane ready for lifting at the shipyard. The chosen configurations for the upcoming lifts were SSL 1 with a boom length of 72 meters, LSL 11 with a boom length of 102 m and LSL 13 with a boom length of 126 m, as well as 22-part reeving. The counterweight consisted of 225 tonnes, as well as an additional 325-tonne Superlift counterweight and 50-tonne central ballast.

Today, as I report in the article, cranes over 800t, and often of 1,000t or higher, are becoming the norm, such as Liebherr's LR 11000 and Tadano Demag's CC 6800-1. But, cranes with a lower nominal capacity like Manitowoc's MLC650 VPC-MAX still have an important role to play on many wind farms.

As Demag's Ingo Noeske explained to me, levelling these large cranes, without pouring excess concrete for hard stands, can pose challenges. His company has developed a clever solution, used first by Sarens, the PC 3800-1. This mounts a lattice crawler upper on a pedestal base, allowing wind farm owners to reduce the amount of concrete they need to pour. A clever transport system, from Faymonville, mounts the crane upper on a towed trailer that can be converted to a self-propelled transporter on site, using the company's APMC system.
